  题目:Filtrations and homological degrees of FI-modules

  报告人:李利平 教授(湖南师范大学)

  摘要: The category FI, whose objects are finite sets and morphisms are injections between them, has played a central role in representation stability theory, a new research area involving algebraic topology, algebraicgeometry, group cohomology, representation theory, combinatorics, and etc.In this talk I will describe the combinatorial structure of FI and introduce homologies and homological degrees of FI-modules. Certain preliminary results as well as quite a lot of unsolved problems will be discussed in details.
